While it's natural and oh so tempting to want to announce big goals, it's smarter to keep them to yourself. In a 2009 experiment at New York University, 163 subjects were given a difficult work project and forty-five minutes to spend on it. Half the subjects were told to announce their goals, while half were told to keep quiet. The subjects who announced their goals quit after only an average of thirty-three minutes, and reported feeling satisfied with their work. Those who kept their mouths shut, however, worked the entire forty-five minutes, and remained strongly motivated. (In fact, when the experiment ended, they wanted to keep working.) Telling others about your big goals makes them less likely to happen, because it creates an unconscious payoff— tricking our brains into thinking we've already accomplished the goal. Keeping our big goals to ourselves is one of the smartest goals we can set.

The psychologists Ken Sheldon and Tim Kasser have found that people who are mentally healthy and happy have a higher degree of "vertical coherence" among their goals—that is, higher-level (long term) goals and lower-level (immediate) goals all fit together well so that pursuing one's short-term goals advances the pursuit of long-term goals.

Okay, you don't actually have to join Alcoholics Anonymous but you can definitely learn something from them: Alcoholics focus on staying sober one day at a time and celebrate these "small wins".

Research has shown that paying attention to "small wins" can help you make progress in many areas of your life.

Small wins are like footholds or building blocks amid the inevitable uncertainty of moving forward, or as the case may be, laterally. They serve as what Saras Sarasvathy calls landmarks, and they can either confirm that we're heading in the right direction or they can act as pivot points, telling us how to change course.

In the acclaimed paper in which Weick described small wins, published in the January 1984 issue of American Psychologist, he used the example of how helpful it is for alcoholics to focus on remaining sober one day at a time, or even one hour at a time. Stringing together successive days of sobriety helps them to see the rewards of abstinence and makes it more achievable in their minds. Elaborating on the benefits of small wins, Weick writes, "Once a small win has been accomplished, forces are set in motion that favor another small win."

Asking people to spend just a minute imagining a close friend standing up at their funeral and reflecting on their personal and professional legacy helps them to identify their long-term goals and assess the degree to which they are progressing toward making those goals a reality.

Candy Chang gives an inspirational TED talk about a project that asked people to finish the sentence: "Before I die I want to…"

Undergrads who wrote letters of encouragement to "at-risk" middleschoolers advising them to persevere and that intelligence "is not a finite endowment but rather an expandabale capacity" became, themselves, happier and better in school for months afterward.

…the mere experience of writing them had a lasting impact on the college students themselves. Months later, the letter writers were still reporting greater enjoyment of school than were other Stanford undergrads. Their grade point averages were higher, too, by a full third of a point on a four-point scale.
